To convert string to camel case in javascript.

camelCase.js

function toCamelCase(str) {
    return str.toLowerCase().replace(/(?:(^.)|(\s+.))/g, function(match) {
        return match.charAt(match.length-1).toUpperCase();
    });
}

Note this JS doesn't appear to work (at least not to covert snake or kebab case to camel case. Appears to want to convert a space delimited string.

For those wanting snake case to camel case, go here: https://gist.github.com/assembledadam/80c97eb03fdc35e1e92ae38537a02ac0

This is Pascal Case (PascalCase), not Camel Case (camelCase). In other words, camel case is when the first letter is lower case.

function toCamelCase(string) {
    string = string.toLowerCase().replace(/(?:(^.)|([-_\s]+.))/g, function(match) {
        return match.charAt(match.length-1).toUpperCase();
    });
    return string.charAt(0).toLowerCase() + string.substring(1);
}

Small changes to the above to allow for kebab and snake case input, as well as proper camelCase rather than PascalCase as @mcarlucci pointed out.

EDIT: I tried the gist from @assembledadam above but it did not seem to work for me.
